Balder fixed oscillating monitor
Description
Balder is a 2½” monitor for fixed installations. It is selfoscillating and powered by water flowing through a special oscillating mechanism. Balder automatically sweeps from side to side. The speed of the sweeps and the elevation could be manually set and also be varied during operation. Balder has a water inlet with a 2½” flange (DN 65). The pipes are casted in two different materials: anodized aluminium or bronze. Parts which are vital for the correct functions, such as swivels are in stainless steel. Innovative piping technology minimizes turbulence and frictional pressure losses. There is a self-cleaning filter at the inlet to the oscillating valve that assures operation even with water containing particles, e.g. rust from the piping. Balder is very compact and weighs only 11.6 kg.
Features
- Compact
- Low weight
- Usable with river and sea water
- Self-cleaning filter protects oscillating valve
- Adjustable oscillating speed and elevation
- Automatic oscillation
- Self-drainage valve
- Works at low temperatures
- Runs with water or foam
- High flows
- Low pressure drop
Operation
Elevation, sweep and speed of oscillation could be preadjusted for automatic operation. When the water flows to the monitor it automatically starts to sweep and operate. During operation the settings can be manually adjusted. It is also possible to release the oscillating function during operation and manually direct the stream within 180° angle.
Application
Balder should be used where among all features the
extremely compact design is beneficial:
- Petrochemical plants
- Aircraft hangars
- Helidecks
- Tank farms
- Loading areas
- Chemical plants
- Offshore platforms
Recommended Foams
- Protein based foams
- AFFF foams
